I'm thinking about putting BandRollers (Woodcraft) on my Delta 14".
I'm using Cool Blocks now and I'm not impressed. Any pro's or con's
out there?

That's a fair amount of money for something I've never found
necessary. Tweaking and technique gets more results than complexity
and expense. They are noisy, and subject to failure. Heck, I've gone
through 2 rear roller bearings in 6 months - I can't imagine having to
replace side rollers that often at $50 (and up) a pop.

For 1/16" blades, I use homemade solid oak blocks soaked in WD-40 with
the blade fully imbedded.

For re-sawing green wood, I use ceramic blocks and a 5/8" 3TPI heavy
alternate set blade. They help cut the resin off the blade.

For everything else, I either use ceramic or cool blocks. I have
noticed that the cool blocks don't fit the holders very well and do
wear somewhat.

The ceramics guides don't wear at all, but you have to be careful
about setting clearances, or they'll spark at the weld when the blade
gets hot (and expands).

Proper tension is also important - the guide on the saw is bogus.

FWIW,
